Application filed September 21, I9f1&. Serial 21o,

Our invention relates to tastenings for hub caps, radiator caps and gasoline tank caps, or the like. 7

One object is to provide an interchange 5 able cap that can be used on. standard cars in any one of the three positions above mentioned.

Another object is method of locking osition.

Other objects will appear from the following description in conjunction with the drawings which form a part of this specification.

Referring to the drawings: 7

Fig. 1 shows the/invention in use as a hub cap.

Fig. 2 is a broken partial section online 22 of Fig. 1.

to provide a quick, sure the cap in the correct is a section taken online 1-4 of Fig. 8 is a sectional View of the invention when used as a cap for gas tanks.

Fig. 9 is a section in plan taken approximately on line 99 of Fig. 8 with springs exposed.

Fig. 10 is a sectional View of the invention when used as a cap for the radiator.

Fig. 11 is a perspective View of the lock- 7 ing spring. v

Fig. 12 is a side elevation of the spring, showing the slightly raised portion on the end of the spring.

In the drawings 1-1 and 1A represents the body or outer shell of the cap which may be formed with a curved or flat surface as desired, both of which are indicated at 2 and 2A, within the cap body is an inner plate, or shell 3 which in Fig. 4 is formed with a depression 4, and portions 3 and 3A are cut at intervals at 5 for the locking springs 6, which protrude through slots in Fig. 3 is an enlarged rear View of the mm- .o rs-e n des al ng rem; cars cap boss 8 fan'dllock in the out. out portions or notches 5, the raised portions 13 riding over the raised ribs 7 of the cap boss 8, which locks the cap in position. The springs 6 are pivoted on pins 9 journaled in cap boss 8 and are held in place by washer 10 and bolt 11 or 11A, and a gasket 12 is inserted between the outer shells 1 and 1A and body portions and 8A toensure an air tight cap when in locked position.

-VVith a twisting movement of the outer shell 11" and 1A the springs 6 open or close to release or look the cap in position. That is, when the cap is placed on the neck to which it is to be applied theends of the springs 6 will pass through the recesses 5. Then by turning the capthe springs are extended or projected outwardly under the flange of the cap, and riding along the ribs 7 will be pressed by said ribs to close contact with the under or inner side of the flange adjacent the recesses 5, thereby clamping the cap to the neck and pressing the gasket 12 against the shoulder of the neck. Thus by spring pressure the cap is held tightly against the neck and loss thereof is prevented. The same cap may be used in any one of the various locations indicated, by providing a neck opening and conformation similar to that described.

- While the construction and arrangement 7 of parts have been described more or less specifically, it is to be understood that ohvious modifications may be made as come within the scope of the appended claims.

We claim: 1'. The combination with a neck having a recessed flange, of a cap fitting upon the neck and having flat springs pivoted thereto and adapted to be entered through the recesses and slidable outwardly to engagement behind the flange by turning the cap.

2. The combination stated in claim 1, the cap having ribs along which the springs ride as theyv slide when the cap is turned, to press the springs in tight contact with the flange. V

3. The combination with a neck having a flange projecting inwardly, with notches at its inneredge, of a capfitting upon the neck and provided with tangential springs pivoted at their inner ends to the cap, and engageable behind the flange of the neck by entering the outer ends of the springs through said notches and turning the cap to project the springs outwardly behind the flange.

4. The combination stated in claim 3, the cap having ribs behind the springs upon which the springs ride when the cap is turned, to clamp the springs against the flan e.

In testimony whereof, we do aifix our signatures.
